Izinzuzo zepulasitiki

Kulula ukucubungula, kulula ukukhiqiza (kulula ukuyilolonga)

Noma i-geometry yomkhiqizo iyinkimbinkimbi impela, inqobo nje uma ingakhishwa kusikhunta, kulula ukuyikhiqiza. Ngakho-ke, ukusebenza kahle kwayo kungcono kakhulu kunokucutshungulwa kwensimbi, ikakhulukazi imikhiqizo ebunjiwe yomjovo. Ngemuva kwenqubo, umkhiqizo ophelile oyinkimbinkimbi ungenziwa.

Ingafakwa ngokukhululekile ngokuya ngezidingo, noma yenziwe ngemikhiqizo esobala

Amapulasitiki angasetshenziselwa ukwenza imikhiqizo egqamile, esobala futhi emuhle, futhi asengakwazi ukufakwa umbala ngokuthanda, okungakhuphula inani lawo lezimpahla futhi kunikeze abantu umuzwa ogqamile.

Kungenziwa ngemikhiqizo engasindi futhi enamandla amakhulu

Uma kuqhathaniswa nemikhiqizo yensimbi neye-ceramic, inesisindo esilula, izakhiwo ezingcono zemishini, namandla athe xaxa (isilinganiso samandla kuya kokuminyana), ngakho-ke ingenziwa ngemikhiqizo engasindi futhi enamandla amakhulu. Ikakhulukazi ngemuva kokugcwalisa i-fiber fiber, amandla ayo angathuthukiswa.

Ngaphezu kwalokho, ngenxa yokuthi amapulasitiki asisindo esincane futhi angonga amandla, imikhiqizo yawo iya ngokuya ikhanya.

Akukho ukugqwala nokugqwala

Amapulasitiki ngokuvamile ayamelana nokugqwala ngamakhemikhali ahlukahlukene futhi ngeke agqwale noma adle kalula njengezinsimbi. Akunasidingo sokukhathazeka ngokuguguleka kwe-asidi, i-alikhali, usawoti, uwoyela, umuthi, umswakama nesikhunta lapho usebenzisa.

Akulula ukudlulisa ukushisa, ukusebenza kahle kwe-insulation

Ngenxa yokushisa okukhulu okuqondile nokushisa okuphansi kwepulasitiki, akulula ukudlulisa ukushisa, ngakho-ke ukulondolozwa kwayo kokushisa nokushisa kokushisa kuhle.

Ungenza izingxenye ezihambayo nemikhiqizo yokuvikela

IPlastiki uqobo luyinto enhle kakhulu yokuvikela. Njengamanje, kungashiwo ukuthi awukho umkhiqizo kagesi ongasebenzisi ipulasitiki. Kodwa-ke, uma ipulasitiki igcwele impuphu yensimbi noma izigaxa zokubumba, nayo ingenziwa ibe ngumkhiqizo ohamba kahle ngogesi.

Ukuncipha kokushaqeka okuhle kakhulu nokusebenza kokunciphisa umsindo, ukudluliswa okuhle kokukhanya

Amapulasitiki anezinto ezinhle kakhulu zokumunca ukushaqeka nezindawo zokunciphisa umsindo; amapulasitiki asobala (njenge-PMMA, i-PS, i-PC, njll.) angasetshenziswa ukwenza imikhiqizo yepulasitiki esobala (njengamalensi, izimpawu, amapuleti ezembozo, njll.).

Izindleko zokukhiqiza eziphansi

Yize impahla eluhlaza epulasitiki uqobo ingashibhile kangako, ngoba ipulasitiki kulula ukuyicubungula futhi izindleko zemishini ziphansi kakhulu, izindleko zomkhiqizo zingancishiswa.

Ububi beplastiki

Ukumelana nokushisa okungekuhle futhi okushisa kalula

Lokhu ngububi obukhulu kakhulu bama-plastiki. Uma kuqhathaniswa nemikhiqizo yensimbi nengilazi, ukumelana nokushisa kwayo kuncane kakhulu. Izinga lokushisa liphakeme kancane, lizokhubazeka, futhi kulula ukusha. Lapho kusha, amapulasitiki amaningi angenza ukushisa okukhulu, intuthu namagesi anobuthi; noma izinhlayiya ze-thermosetting, izobhema futhi ihlube lapho idlula ama-200 degrees Celsius.

Njengoba izinga lokushisa lishintsha, izakhiwo zizoshintsha kakhulu

Akusho ukuthi ukushisa okuphezulu, noma ngabe kuhlangabezana nokushisa okuphansi, izakhiwo ezahlukahlukene zizoshintsha kakhulu.

Amandla aphansi emishini

Uma kuqhathaniswa nomthamo ofanayo wensimbi, amandla womshini aphansi kakhulu, ikakhulukazi kwimikhiqizo emincane, lo mehluko ubonakala kakhulu.

Iyakwazi ukugqwala ngamakhemikhali akhethekile namakhemikhali

Ngokuvamile, amapulasitiki awangenwa kalula ukugqwala kwamakhemikhali, kodwa amanye amaplastiki (njenge: PC, ABS, PS, njll.) Anezici ezimbi kakhulu kulokhu; ngokuvamile, izinhlaka ze-thermosetting zimelana nokugqwala.

Ukuqina okungalungile nokuguga okulula

Noma kungamandla, ukucwebezela komhlaba noma ukungafihli lutho, akuhlali isikhathi eside, futhi kungena ngaphansi komthwalo. Ngaphezu kwalokho, wonke amapulasitiki ayesaba imisebe ye-ultraviolet nokukhanya kwelanga, futhi azoguga ngaphansi kwesenzo sokukhanya, umoya-mpilo, ukushisa, amanzi nemvelo yomkhathi.

Isengozini yokulimala, uthuli nokungcola

Ubulukhuni bendawo yamapulasitiki buphansi ngokuqhathaniswa futhi bonakaliswa kalula; ngaphezu kwalokho, ngoba iyisivikelo, ishaja ngogesi, ngakho-ke kulula ukungcoliswa ngothuli.

Ukuzinza kobukhulu obubi

Uma kuqhathaniswa nensimbi, ipulasitiki inezinga eliphakeme lokuncipha, ngakho-ke kunzima ukuqinisekisa ukunemba kobukhulu. Endabeni yomswakama, ukumuncwa komswakama noma ukushintsha kokushisa ngesikhathi sokusetshenziswa, usayizi kulula ukuwuguqula ngokuhamba kwesikhathi.
